A Perspective on Muscle Synergies and Different Theories Related to Their Adaptation

The human motor system is a complex neuro-musculo sensory that needs further investigations of neuro-muscular commands and sensory-motor coupling to decode movement execution. Some researchers suggest the central nervous (CNS) activates small set modules termed muscle synergies simplify control. Further, these form functional building blocks as they can explain neurophysiological characteristics movements. We identify extract from electromyographic signals (EMG) recorded in laboratory by using linear decomposition algorithms, such principal component analysis (PCA) non-Negative Matrix Factorization Algorithm (NNMF). For past three decades, hypothesis has received considerable attention we attempt understand apply concept clinical settings rehabilitation. In this article, first explore synergies. then present different strategies adaptation CNS employs accomplish goal.
